There is nothing more frustrating than a MIG gun trigger that doesn't feel right. Maybe it sticks, maybe it doesn't click, or maybe it's just broken entirely. The Miller 260507 Actuator Push Button Assembly is the exact part you need to fix the trigger mechanism on your Miller MDX series MIG gun. Don't struggle with a faulty torch that compromises your weld quality or causes hand fatigue; swap out the worn actuator and get back to laying smooth beads.

This isn't a generic knock-off; it is the genuine Miller part designed to fit your gun's handle perfectly. Installation is straightforward, allowing you to open up the handle case, swap out the old button assembly, and close it back up in minutes.

It is built tough to handle the daily abuse of the shop floor, ensuring your gear is ready to work whenever you are.

Whether you are a professional fabricator or a serious hobbyist, keeping your equipment in top shape is part of the job. A broken trigger button can stop a project in its tracks.
